I recommend Ocean Kids United Pediatric and Adolescent Clinic.

Located in Myeongji-dong, Busan This is Ocean Kids United Pediatric and Adolescent Clinic. The hospital is spacious and the doctors are friendly. The wait time is a bit long, but I still end up going here. The closing time is longer than other hospitals, and they sometimes provide general adult care as well. I even got my COVID-19 vaccination here. So I go here often.
